Application filed December 11, 1912. Serial No. 736,100.

To al 'wizom z'i may, concern lie it known that. 1, CHARLES KOEHLER, a citizen of the Republic of Switzerland, residing at lassaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Fabric-Frames for Embroidery-Machines, of which the following is a specification.

The object of this invention is to provide a frame for holding the fabric or fabric pieces in embroidery machines which will be an improvement on such frames now used in that it will possess all of certaln features of advantage of which at best only, one or some are pos essed by any one type of such frames now used, to wit: that the improvedframe will be at once light, simple and strong in construction, permit either large or small designs to be worked out-in each fabric held thereby, may be used to quite the same advantage in a shuttle machine as in a hand machine, and not only facilitate the application thereto and removal therefrom of the fabric pieces but hold them always uniformly stretched as to the whole of the portion being worked upon.

In the accompanying drawing, F gure 1 1s fa planview. .ofasfragmensofihe. lmproved frame, showing two of the fabridholders" partly in section; Fig. 2 is a vertical sectional view of the frame, showing a fabric holder in side elevation; Fig. 3 is a horizontal sectional view in a plane between the upper and lower stripof the frame; and,

Fig. 4 a perspective view of one of the fabric holding clips.

a c designates two parallel substantially sheet-like strips which, being parts of the improved frame, afford a convenient and effective hold to clamps or the like whereby tl frame is secured to the frame of the e1nbroidery machine. These are arranged with their front faces nearly in the same place, as seen in Fig. The upper strip has the elongated apertures c, regularly spaced, and it is somewhat thicker and hence stiffer than the lower frame; it is thus well adapted as the part of the frame by which the latter is handled in transrmrting it to and from the 59 machine. 31

(Z desi nates the fabric holders, each being an endless or continuous member having a couiiiuums peripheral groove a; they are preferably of oval shape. as shown. Each fabric holder is uuicd to each Strip a'fa in some way calcdlatcd to produye a iigi d'joint between them, as by placing the extremity of each holder against the front (broad) face of the strip and driving two screws fthrough the holder int-o the strip. Ilhe holders have recesses 1) receiving the lower strip, the object of which is to reduce the thickness of the entire frame, thus affording room for the proper working of the horizontally, moving needles in the embroidery machine, it being M noted that thg holders themselves with the same purpose in view are made as thin as possible conditioned upon their having such thickness (or width of peripheral surface) as is needed to secure the proper gripping action for the bands (to be described) which embrace them and hold the fabric-pieces thereto.

'The various holders are preferably constructed of aluminum; the strips a a are formed of. steel. Thus constructed, the frame proper is a structure which, while strong and durable, may not only include as large a number of holders as could be required but is still light enough to be handled with facility and convenience.

The fabric-pieces, designated 9, are held stretched over the holders by the endless constricting bands h or i. The bands 71. (one in Fig. 1) are designed for securing fabrics such being shown on the left-hand holder of coarser texture to the .holderspeach ot these consists of a continuous or endless spirally wound wire. The bands ?I are designed for securing in place fabrics of fine textures (one such being shown on the right-hand holder in Fig. l) and each includes a piece of non-extensible wire having its ends hooked to each other and an elastic rubber tube 2' forming a casing for the wir'e. In both cases the band is too smal in diameter to be fitted around and into the groove of the holder without distention in the form h, accomplished by longitudinal extension of the band and in the form '2', by compression of the elastic tube or casing 2' ln fitting the fabric-pieces (for instance, handkerchiefsl in place each piece is individually secured by a clip 7', such as that shown in Fig. l, to the upper strip (1. Then, having if necessary, in the manner shown in Fig. .3, rolled up that part ofa-the fabi 'ic which is not to be embroidered, the remainder of the piece is laid ovcr the adjoining holder. Then, keeping the material smooth throughout, the band is placed upon the mater i' l and then forced around .t-lic' froul edge I worked is of pccu iar advantage not only in" that it holds the material firmly and keeps it. evenly distended while being embroidered, but in that it greatly facilitatesv and expedites the operation of applying the fabricpieces to the frame; The removal of. each band in order to release the fabric-piece heldthereby is readily accomplished, preferably by beginning the removing operation at one side of the holder.

Having thus fully described my invention, what I claim'as new and desire to secure by Letters Patent is 7 1. A fabric holding frame for an em broidery machine comprising parallel spaced substantially sheet-like strips, rigid fiatopen fabric holders arranged side by side and spaced from each other and each rigidly secured against corresponding-broad faces of 1 v 4 Witnesses:

both strips, and a continuous constricting band embracing each holder, the fabric being adapted to be placed over each holder both strips,- each ho grooved, and a continuous constricting band embracing each holder-and continuously ocand there held stretched over the same by thereupon fitting, the corresponding band to the holder overand around the fabric, sub- I stantially as described. 2. A f brie holding spaced from eachother and each rigidly secured against corresponding broad faces of dcr being peripherally cupying the groove thereof, the fabric'being iadapted to be placed over each holder and holder over vand around the fabric, substantially as described.- 7 i In testimony Whereo in presence of two witnesses.
